I spoke to some one on now TV help chat back in mid of October, as it usually airs a week behind the US, but it had been nearly a month. They said that they were not renewing the licensing for Greys, so there is no air date what so ever. No other Uk channels or subscribers have picked it up .... looks like it’s over for us in the UK 😩
Well I'm highly disappointed with NOWTV, Greys Anatomy has a huge following in the UK, it's shame that they've decided to part ways. It's the only reason why I kept my NOW TV account open. Thankfully Amazon Prime has seasons 1-15 on demand, hopefully they'll have season 16 soon.
This will be a decision by Sky and Now TV just have to follow suit. Now TV can only show what Sky has bought rights for.
Looks like the rights weren't purchased for the usual week delay, but more likely some time in the new year.
